DIY 5-Gallon Bucket Slow Sand Filter¶
BioSand & Media Filters • Est. CapEx: Low-cost / Locally fabricated
Technical Overview¶
A small-scale, low-cost water filter made from a 5-gallon bucket, intended for household use. It uses sand and biological layers to improve water quality, though real-world results showed marginal effectiveness.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | BioSand & Media Filters |
| Capital Cost | Low-cost / Locally fabricated |
| Primary Mechanism | Water flows by gravity through a sand layer where a biofilm (schmutzdecke) develops; particulates are trapped and pathogens are reduced through biological processes. Requires rough container walls to prevent channeling. |
| Target Scale | Household / Village Cluster |
| Standard Lifespan | 10 - 20 Years |
